Im sure most enthusiasts are interested in tire reviews because theyre always looking for that ‘next set of tires’. Be it for spirited driving on the roads or weekends at the track, drivers are always looking for a set of tires that suit their budget AND application. Even I get a headache when Im looking for that ‘next set’. I currently use a set of Bridgestone Potenza RE11, which I will review in future.
Now my review on the AD08s are going to be only about their track performance, because quite honestly, Ive only used them on the track, when I participated in the 2010 Yokohama Philippine GT (here). The good news is, I was able to use them in both dry AND wet conditions. Keep in mind that this is my personal opinion, drivers with different cars or driving styles may have a different opinion.
The car I drove was a race prepared Ford Focus 1.8, front wheel drive (FF), with 125whp. Tire size varied, because during testing, it was 205/50R16, but the control was 195/55R15. I will describe the differences between the sizes later.
This tire is extremely suited to dry track conditions, with its softer compound and large tread blocks, there is ALOT of grip. However, even with 125whp, you CAN still get wheel spin exiting corners if you get it wrong. Response is also very high, translating every steering input into work done. If you do exceed the tire’s limits, it will breakaway very progressively. Braking is surefooted and communicates very well if youre going to lock up.
Its also very good when its wet, being stable in most conditions, not suddenly throwing you off. However, with its very high response attribute, I strongly encourage drivers to be very smooth with their inputs in the wet. Quick steering inputs will cause you to lose traction.
During testing, the 16 inchers had better ultimate grip due to the larger tread width, but with the shorter sidewall, the tire responds so quickly that it was difficult to find or stay at the limit. Although the 15 inchers had less grip overall, the taller profile gave the sidewall just a little more flex to increase communication and made it easier to stay around the limit, allowing me to utilize them better.
For those not willing to commit to semi slicks, the AD08 is a good choice for drivers that want to stick with street tires.
